Abstract: A novel family of crystalline, microporous gallophosphate compositions is synthesized by hydrothermal crystallization at elevated temperatures from gallophosphate gels containing a molecular structure-forming template. The family comprises distinct species, each with a unique crystal structure. Calcination removed volatile extraneous matter from the intracrystalline void space and yields microporous crystalline adsorbents with pores, the dimensions of which vary, among the individual species, from about 3A to 10A in diameter. The compositions represent a new class of adsorbents of the molecular sieve type, and also exhibit properties somewhat analogous to zeolitic molecular sieves which render them useful as catalysts or catalyst based in chemical reactions such as hydrocarbon conversion.

Abstract: A cobalt-molybdenum catalyst and a method for preparing same, said catalyst useful for the hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) of distillates of petroleum. The catalyst is supported by aluminum phosphate or an aluminum borate. In a preferred embodiment the catalyst has a low cobalt content, between 0.5% and 2.0% by weight calculated as CoO, and a molybdenum content of between 10% and 20% by weight, calculated as MoO.sub.3. The phosphorus or boron compounds added to the aluminum before the impregnation of the active metals prevents the formation of undesirable compounds of the CoAl.sub.2 O.sub.4 type, which is inactive in HDS.

Very small crystals, highly dispersed on the surface of the catalyst, whose formula is CoMoO.sub.4, are responsible for the stability and the high level of activity in HDS and HDN which results.
